超声造影评价颈动脉粥样斑块稳定性

Evaluating carotid atherosclerotic plaques stability with contrast-enhanced ultrasonography

目的应用实时超声造影技术评价颈动脉粥样斑块的稳定性与临床症状的关系。方法应用实时超声造影检查50例颈动脉粥样斑块患者，分析粥样斑块的造影显像情况与患者临床症状的关系。结果50例颈动脉粥样斑块患者中23例有明显临床症状及体征的粥样斑块全部显影；27例无明显临床症状的患者中，15例稀疏显影，12例无显影。结论超声造影能实时观察颈动脉粥样斑块内的微循环情况，无创性评价颈动脉粥样斑块的稳定性。

Objective To evaluate the relationship between carotid atherosclerotic plaques stability and the clinical symptoms of carotid atherosclerosis by contrast-enhanced ultrasonography. Methods Fifty patients with carotid atherosclerotic plaques were examed with contrast-enhanced ultrasonography, the contrast agent visualization of the carotid atherosclerotic plques were analyzed and compared with their clinical symptoms. Results Twenty-three patients who suffered from obvious clinical symptom were entirely visualized. Twenty-weven patients had not apparent clinical symptom, of these patients, 15 were sparse visualized, there was no visualization in other 12 patients. Conclusions Contrast-enhanced ultrasonography can real-time observe microcirculation in carotid atherosclerotic plques, and assess the stability of carotid atherosclerotic plaques.
